I mostly avoided the Ohio Turnpike heading back to Michigan and swung up to OH 2 instead. I took US 23 out of Ohio to check the multiplex of US 223. US 223 is pretty well signed from the start point just south of the Ohio State Line on US 23 up to where it splits off in Michigan.

- Correct that US 53 came into Eveleth from the north via Grant Ave. South of town (really more like southeast of town), there is an abandoned road alignment visible from the southbound on-ramp from MN 37 that shows part of US 53's original alignment before the 4-lane was built. Near Eveleth Airport is a road named "Miller Trunk Road" that is also part of the original alignment.

- As noted in another thread, the major relocation project is for US 53 so that the land underneath existing US 53 between MN 135 and 2nd Ave W in Virginia can be mined.

Part 2; MN 1 east of US 53, the Soudan Mine, and mystery of what could have possibly been an extension of US 169 to Lake Superior:
